Material name
2004 on a placard, orange panel or shipping paper
It points to the ERG 2024 entry “Magnesium diamide” and to Guide 135. On a numbered orange panel, 2004 is the lower number (how to read an orange panel).
ERG 2024 markings for 2004
2004 is highlighted in green, so ERG 2024 Table 1 (Initial Isolation and Protective Action Distances) has an entry for it: “Magnesium diamide (when spilled in water)”. Hazora shows those distances in the app, not on this page. “When spilled in water” means the material produces large amounts of toxic inhalation hazard (TIH) gases when spilled in water. Table 2 (Water-Reactive Materials Which Produce Toxic Gases) lists the gas produced: NH3 (ammonia). Its guide number 135 has no P.
